Late Ordovician bentonite database

Dataset of all Late Ordovician dates analysed in bentonites. Used in Figure 1 of "Late Ordovician climate change and extinctions driven by elevated volcanic nutrient supply" by Longman et al., Nat. Geosci. (2021)本数据集涵盖所有经斑脱岩（bentonites）分析得到的晚奥陶世（Late Ordovician）定年数据。该数据集被应用于Longman等人2021年发表于《自然·地球科学（Nature Geoscience）》的论文《火山养分供给提升驱动的晚奥陶世气候变化与生物灭绝》的图1中。
